Amir H. Mohammadi, Auteur ; Veronica Belandria, Auteur ; Dominique Richon, Auteur |In this communication, we examine the possibility of clathrate hydrate formation of toluene and o-, m-, or p-xylene with methane as help gas. An isochoric pressure-search method was used to measure hydrate phase equilibrium boundaries. The relia[...]

Ali Eslamimanesh, Auteur ; Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |Accurate knowledge of the sulfur content of gases is a significant factor for prediction of the sulfur precipitation conditions in production of sour natural gases. However, because the concentration of sulfur in the gas phase is very low, the m[...]

Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |In this communication, we report an artificial neural network algorithm for estimating sulfur content of hydrogen sulfide at elevated temperatures and pressures. This model eliminates any need for characterization parameters, due to the tendency[...]

Mehdi Mehrpooya, Auteur ; Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |In this communication, we report an extended artificial neural network algorithm to estimate sulfur content of sour/acid gases. The main advantage of this algorithm is that it eliminates any need for characterization parameters, due to the tende[...]

Amir H. Mohammadi, Auteur ; Ali Eslamimanesh, Auteur ; Dominique Richon, Auteur |In this paper, we present two different approaches to represent/predict the gas hydrate phase equilibria for the carbon dioxide, methane, or ethane + pure water system in the presence of various types of porous media with different pore sizes. T[...]

Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |In this communication, experimental hydrate dissociation data for the ethane, carbon dioxide, or hydrogen sulfide + ethylene glycol + water system are first reported at 0.1, 0.2, 0.35, and 0.5 mass fractions of ethylene glycol in aqueous solutio[...]

Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |In this work, we report ice−clathrate hydrate−gas equilibrium data (dissociation data) for the air, oxygen, nitrogen, carbon monoxide, methane, or ethane + water system. The equilibrium data for methane and ethane clathrate hydrates are compared[...]

Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |In this communication, we report ice―clathrate hydrate―gas equilibrium data (dissociation data) for the argon + water and carbon dioxide + water systems in the temperature ranges of (264.3―271.2) and (260.2―270.7) K, respectively. The equilibriu[...]

Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |A mathematical model based on feed-forward artificial neural network technique, which uses a modified Levenberg−Marquardt optimization algorithm, has been developed to estimate the solubility of a pure hydrocarbon hydrate former in pure water be[...]

Amir H. Mohammadi, Auteur ; Ali Eslamimanesh, Auteur ; Dominique Richon, Auteur |Asphaltene precipitation is traditionally modeled using the Flory–Hüggins polymer solution theory. The existing thermodynamic models, generally, do not take into account the aggregation/association phenomena in the system. This work aims at prov[...]

Phase equilibria of clathrate hydrates of cyclopentane + hydrogen sulfide and cyclopentane + methane
Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |In this work, experimental hydrate dissociation data for the hydrogen sulfide + cyclopentane + water and methane + cyclopentane + water systems are reported in the temperature ranges of 295.4−310.0 K and 284.8−299.3 K, respectively. The experime[...]
